Matt Riddle replaces Stephen Thompson, meets Besam Yousef at UFC 154

Fresh off a 90-day suspension due to a failed drug test, Matt Riddle (6-3 MMA, 7-3 UFC) has stepped up as a late replacement for injured Stephen Thompson (6-1 MMA, 1-1 UFC) and now meets welterweight Besam Yousef (6-1 MMA, 0-1 UFC) next month at UFC 154.

UFC officials today announced the change.

UFC 154 takes place Nov. 17 at Montreal's Bell Centre.

The night's main card, including UFC welterweight champion Georges St-Pierre vs. interim titleholder Carlos Condit, airs on pay-per-view following prelims on FX and Facebook. Riddle vs. Yousef, which is the card's 13th fight, is slated for the Facebook stream.
